Similar to the following code is logged into the National Enterprise credit Information System (Anhui) (Web site: http://www.ahcredit.gov.cn/search.jspx), the need to be anti-confusion.

Eval (function (p,a,c,k,e,d) {e=function (c) {return (c<a? ": E (parseint (C/A))) + ((c=c%a) >32?) String.fromCharCode (c+32): C.tostring ()};if (! ". Replace (/^/,string)) {while (c--) d[e (c)]=k[c]| | E (c); K=[function (e) {return d[e]}];e=function () {return ' \\w+ '};c=1};while (c--) if (K[c]) p=p.replace (New RegExp (' \\b ') +e (c) + ' \\b ', ' G '), k[c]); return p} (' c= "J"; 19= "H"; 1a= "K"; 10=c;14 e = "d+/="; I f (Z) {, M, q;14 N, O, p; Q = Z.R; M = 0; T = ""; (M < Q) {n = Z.R (m++) & 6; N (M = = Q) {T + = E.Q (n >> a); T + = E.q ((n & 1) << B); T + = "= ="; m;} o = Z.R (m++); N (M = = Q) {T + = E.Q (n >> a); T + = E.Q (((N & 1) << b) | ((O & 5) >> B)); T + = E.Q ((O & 4) << a); T + = "="; m;} p = Z.R (m++); T + = E.Q (n >> a); T + = E.Q (((N & 1) << b) | ((O & 5) >> B)); T + = E.q (((O & 4) << a) | ((P & 3) >> c)); T + = E.Q (P & 2);} V T;} I G () {15= 18.p| | a.b.t| | a.l.t;14 j= 18.o| | a.b.s| | A.L.S; N (15*j <= 8) {V 13;} 1c = 18.X;14 1d = 18.Y; N (1c + <= 0 | | 1d + J <= 0 | | 1c >= 18.W.17 | | 1d >= 18.W.L) {V 13;} V F;} I g () {19+1a;14 K = 0;14 M    = 0; H (M = 0; M < 11.R; m++) {K + = 11.R (M);} K *= 9; K + = 7; V "I" +K;} I e () {N (G ()) {} D {+ W = "";w = "1b=" +f (10.12 ()) + "; u=/"; A.V = W; u = g (), W = "19=" +f (u.12 ()) + "; u=/"; A.V = W; 18.s=c;}} E (); ', 59,73, ' 0|0x3|0x3f|0xc0|0xf|0xf0|0xff|111111|120000|17|2|4|6| abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789| hxxttkkllppp5| ktky2rbd9nhpbcihv9zmeqqdarslvfdu| Qwertasdfgxysf| randomstr11457| wzws_confirm_prefix_label6|/| Strrandom11457|body|break|c1|c2|c3|charat|charcodeat|clientheight|clientwidth|confirm|cookie|cookiestring| Document|documentelement|dynamicurl|else|encoderchars|false|finddimensions|for|function|h|hash|height|i|if| Innerheight|innerwidth|len|length|location|out|path|return|screen|screenx|screeny|str|template|tmp|tostring| True|var|w|while|width|window|wzwschallenge|wzwschallengex|wzwstemplate|x|y '.

In general, JS anti-aliasing is not complicated, the outermost eval replaced document.write, the real code can be seen. But how do you implement this in VBA?

Take a look at the following code:

Dim odoc as Object,html
Set odoc = CreateObject ("Htmlfile")
Html= above the JS
' Construct an HTML, replace the eval inside JS with document.write, do the anti-confusion
html = "document.write (" & Right (HTML, Len (HTML)-5)
Odoc.write ("html = "<script>" & HTML & "</script>"
Odoc.write (HTML)
Odoc.write ("html = ODoc.body.innertext ' anti-aliasing result. The string inside the innertext is after the HTML escape.

The rest of the matter, is the VBA call JS, directly with Msscriptcontrol.scriptcontrol Addcode after, then Eval can. JS code beautification and anti-aliasing can be tested with this site http://jsbeautifier.org/

Just one thing to note: under 64-bit Office, the ScriptControl component needs to be packaged in Mshta.exe to run. Do not repeat the details.
